SPECIFICATION forming part of Letters Patent No. 743,528, dated November10, 1903.

a Application filed September 2, 1902. Serial No. 121.777. (No model.)

To aZZ whonz it may concern.-

Be it known that I, JOSEPH Ln REAU, dit LHEUREUX, a subject of the Kingof Great Britain, residingat Windsor, county of Essex, Province ofOntario, Canada, have invented a certain new and useful Improvement inApparatus for Flushing and Ventilating Urinals; and I declare thefollowing to be a full, clear, and exact description of the invention,such as Will enable others skilled in the art to which it pertains tomake and use the same, reference being had to the accompanying drawings,which form a part of this specification.

My invention relates to apparatus for flushing and ventilating urinals;and to this end it consists in the novel and peculiar construction ofthe several parts thereof and their combination for accomplishing theseresults in the manner hereinafter described, and indicated in theclaims.

Referring to the accompanying. drawings, Figure 1 is a sectionalelevation of an apparatus embodying my invention and so much of aurinal-bowl as is necessary to illustrate its connection therewith. Fig.2 is a side elevation of thesame looking from the left of Fig. 1. Fig. 3is an enlarged sectional detail of the end of the water-pipe andspraying-nozzle. Fig. 4 is a detail showing the construction of thespindle.

L is the bowl of the urinal.

F is a casing located a short distance above the bowl L.

B is a large pipe opening at its lower end to the interior of the bowl Land at its upper end to the interior of the casing F. The pipe B turnsfrom the vertical to the horizontal after it has entered the casing F,and the pipe is of a diameter equal to the distance from the front tothe rear wall of the casing F, so that the upper part of the bentportion of said pipe forms a curved partition J and the lower part acurved partition K. The partitions K and J extend to about the centerline of the casing F.

I is a partition extending from the wall of the casing F opposite andabove the partitions J and K.

Gis asmall pipe communicating at its lower end with the bowl L and atits upper end with the interior of the casing K at its lowest part.

11 is a pipe opening to the outer air from the top of the casing F.

A is a pipe for delivering water under pressure. The pipe A is providedwith a regulating-cock a, extends into the pipe B, and terminates in avertically-extending nozzle N.

C is a spindle extending axially through the nozzle N, provided with ascrew-thread at its lower end adapted to engage screwthreads in thenozzle N. Said nozzle is provided with a mouth at its upper end.

D is an inverted conical plug whose apex is screwed to the upper end ofthe spindle O in such a way that it can be detached and removed from thecasing N for cleaning, while the spindle can also be withdrawn byunscrewing it from the base of said casing, as will be clearly seen inFig. 4. After assembling the parts of this nozzle the upwardwater-discharge may be so adjusted by turning the screw-threaded base ofthe spindle in the threaded base of the nozzle as to cause the water toissue. as a conical sheet of water,

entraining and carrying up a large volume of air through the pipe B andinto the curved end thereof, issuing from which the air finds an outletat the top, while the water impinging on thecase-walls and partition 1drops by gravity through the flush-pipe G into the bowl.

The operation of the above-described device is as follows: The positionof the plug D is adjusted so as to alford the required opening from thenozzle N. The water is then turned in by means of the cook a. A film,sheet, or spray of water is projected from the mouth of the nozzleapproximately as indicated by the dotted lines at d, Fig. 1. The watercarries with it a large amount of air, which is drawn from the bowl,forced into the casing F, and passes out'ofthe vent-pipe H; The waterpasses into the casing F, is prevented from passing to the pipe H by thepartition 1, falls by gravity to the bottom of the casing F, and runsdown through the pipe G to flush the bowl L.

What I claim is 1. A ventilating and flushing apparatus for urinals,consisting-of a bowl, a separatingchamber elevated above the bowl, avertical air-pipe connection between the two, a waterjet and nozzleadapted to draw a current from the bowl, means in the path of thedischarge from the upper end of the vertical air-pipe arranged to breakthe jet to separate the water from the air in said separating-chamher,and a pipe containing an unimpeded passage through which the waste waterreturns to the bowl, substantially as described.

2. A ventilating and flushing apparatus for urinals, consisting of abowl, a separatingchamber elevated above the bowl, an air-pipeconnecting the bowl thereto, means for projecting a flaring sheet ofwater in said pipe, such sheet arranged to actuate a current of airdrawn from the bowl and force it through the separating-chamber and outthrough a vent-pipe in the top thereof, and means in the path of thedischarge from the air-pipe arranged to break the jet in said chamber toseparate the water from the air, substantially as described.

3. A ventilating and flushing apparatus for urinals, consisting of anelevated chamber, a vertical pipe connecting the bowl with the elevatedchamber, a radial abutment in said chamber arranged in the path of thedischarge from said vertical connecting-pipe to arrest the upflow ofthe-Water projected against it, thereby separating it from the entrainedair; a vertical pipe connecting the bowl with the elevated chamber, theupper end of said pipe projecting into it and curved to project theWater against the abutment, and a waste-pipe connecting the chamber withthe bowl for flushing it with the waste water, substantially asdescribed.

In testimonywhereof I sign this specification in the presence of twowitnesses.
